    Kill dhclient like the message says, and try again.

    Well you have to kill the actual dhclient process. The number might change depending on certain factors.
    Start up BT but do not start networking. Then follow the guide you are using.

    wlan0 Ralink 2573 USB rt73usb - [phy0]SIOCSIFFLAGS: No such file or directory
    This looks like the same error a lot were having after the upgrade a while ago.
    Not sure which wireless card you are using, however I was using the WUSB54GC and
    got the same error.
    Appeared that the drivers somehow got fubarred with the update-upgrade.

    Have you recently done a apt-get upgrade and the apt-get distupgrade ?
    If so the below may help you ;

    Try getting hold of a fresh rt73.bin file ;
    > either download from ralink and extract the rt73.bin, or ;
    > boot a live usb/dvd with backtrack4 and copy the rt73.bin from /lib/firmware-2.6.30.9/ to a flashdrive)

    Then when in your VM, copy it to the location;
    /lib/firmware-2.6.34/


    Then try again.

    For your reference as well ;
